Thel sole clips are mounted in any desired hole I3 by merelypassing the wing I 6 through the slotted series of holes, moving theneck up or down to the desired hole and then turning the sole clip to ahorizontal position, which causes the neck I5 to bind in the hole, dueto the fact that the width of the neck and the diameter of the hole aresubstantially the I6 frictionally engages one side of the toe iron,while the toe clip frictionally engages the other side. The sole clipsare slightly convex on the sole engaging face, in order to facilitateentry of the sole under the same.

Referring now to the modied form of toe irons disclosed in Figs. 5 and 6of the drawings, the numeral I1 indicates the toe irons disposed inforwardly converging relationship. Flat, transverse tongues I8 supportthe toe irons and extend across the ski in side by side relationship andare secured in such position and slidable relative to each other by agrooved anchor plate I9 rigidly mounted to the ski by suitable screws.Adjacent edges of the tongues are formed with matching semi-circularnotches 20. A screw 2l extends through the anchor plate, through thecircular opening formed by a matching pair of notches and is thenthreaded in a metallic thimble 22 xedly embedded in the ski I.

To adjust this form of toe irons, the screw 2| is removed, the tonguesmoved in opposite directions until the toe irons are in proper positionand a pair of notches 2D are in matching rela- Y' screw is replaced andtionship and then the tightened. The screw being threaded into theembedded thimble prevents splitting of the ski and stripping of thescrew hole which would ultimately occur if a Wood gaged in the wood ofthe ski. The heel strap and a buckle unit comprises a flexible metallicheel strap 23, having spaced heel clips 24 projecting inwardly at rightangles to the strap. The strap 23 is also provided with a tighteningclamp 25 of usual construction.

Each end of the metallic heel strap 23 is en larged as at 26, and Yeachenlarged portion is provided with two spaced, rectangular openings 21.Sliding rings 28 are mounted on the enlarged portions 26, adjacent theopenings 21, to form the complete buckles.

Separate connecting straps 29 are passed through slots 30 in each toeiron and the two free ends of the doubled straps are connected to thebuckles as follows: The inner end of each connecting strap is passedfrom the inside of the enlarged portion 26 through the rearmost opening21, is extended around the adjapassed back through the same opening 21and the end allowed to remain free. The outer ends of the straps aresimilarly passed through the foremost opening 21. To tighten the strap29 and draw the heel strap tightly about the heel of the ski boot, therings 28 are drawn rearwardly, the connecting straps drawn taut and therings then moved forward until the' straps are frictionally engagedagainst the forward side of the opening 21. Then, any pull on same size.Also, the wingV screw were used and enstraps 29 will tend to furthertighten the straps in the buckle units, as when the tightening clamps 25are closed. When the straps 29 and heel strap 23 are tightened, the heelclips 24 enis to use the skis. preferred or modified form) are firstadjusted laterally of the skis to snugly engage the sole of the boots,such adjustment being accomplished in the manner heretofore described.Then the sole clips are adjusted so as torengage against the upper edgeof the sole and hold the sole from relative vertical movement away fromthe ski. In the eventthat sole clips are not used, a toe strap may beused instead, as indicated at T in Figurel 1.

Afterthe toe irons and clips are adjusted, the heelstrap is placed aboutthe heel of the boot, with the heel clips extending over the upper edgeof the heel, the connecting straps are tightened as heretofore describedand lastly, the tightening clampiis closed.

The toe irons Vare preferably of malleable metal, so that their angle ofconvergence may be changed to conform to various shapes of boot toes.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein. Y

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not forni a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent is:

1. In a ski binding including toe irons, means mounting the toe irons onthe ski for relative lateral movement, and means to move the toe ironsin opposite directions relative to each other; said last named meanscomprising a laterally immovable but rotatable transverse bolt mountedadjacent the forward ends ends of the bolt being threaded with right andleft-hand threads, respectively; threaded on the Vends of the bolt, theforward end of each toe iron being notched and engaging over the groovedportion of the corresponding nut.

2. In a ski binding including toe irons, means mounting the toe irons onthe ski for relative .teral movement, Vand means to move the toe ironsin opposite directions relative to each other; said last named meanscomprising a laterally immovable but rotatable transverse bolt mountedadjacent the forward ends of the toe irons, the ends o-f the bolt beingthreaded with Y*right and left-hand threads, respectively; and

means on the forward end JEROME E. BARIEAU.
